“Thank you to Dan, Bridget and Nick who went above and beyond the call to acquire my husband and I a rental car on Thanksgiving weekend! 5 hours we waited for a solution to our van which is still not solved...but 13 hours later on a trip that should have taken 5 and we are with family in Chicago. We do not live in Lafayette, but while waiting in their nice waiting room, I listened to each one of them deal with their customers in such a thorough and polite manner. What a great company...I would highly recommend this group of people! Thank you all for your genuine concern for two strangers...thank you to Toyota and Eric - what a blessing!!! I hope I got all of your names right...but you know who you are. Thank you and We hope you have a wonderful Thanksgiving!"
